If you see any business moguls running around with what look like skater knee pads with cables running up to mobile devices, don't be surprised. These knee pads generate up to five watts of electricity for every step the user takes, without any noticeable effect on the wearer. When harnessed, this device can power and charge anything from iPods to Blackberries. The device mainly gains power, much like an average hybrid vehicle, during the "deceleration phase" of walking. A Canadian company called "Bionic Power" recently patented this device, and hopes to commercialize it as soon as they can.
